Q: how to connect iMac to overhead projector

I wanted to show the albums in iPhoto in my school, but couldn't find a way to hook it up with the overhead projector. People said I probably need HDMI, but my iMac has no HDMI port, so I wonder if any cabe and/or adapter I need to do the job.

iMac, OS X Yosemite (10.10.1)

Welcome to Apple Support Communities

First you need to know what ports the projector has got. The most classic ports are VGA, DVI or HDMI, and you need adapters for all of them. If you want the best image quality and the projector has got a HDMI port, use HDMI.

There are different adapters you have to buy depending on the port you want to use, such as the Mini DisplayPort to DVI adapter, Mini DisplayPort to VGA adapter or Mini DisplayPort to HDMI adapter (there is not an official adapter), apart from a DVI, VGA or HDMI cable.
